' description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of thedrawing is a plan viewl of my invention. Fig. 2 is a vertical transverse section of the same.

This invention has for its object certain valuable improvements in the general construction of stave-join ters.

In the drawing, A represents the main frame, supportin g in suitablejonrnals B the concave cutting-cylinders C, to which are bolted the knives D. E represents the bed-plate, upon which are placed the staves to be iinished by the knives D. Said bed-plate is convex at its forward edge, and recessed at the back part. It is suliported on standards F, which are hun g on the rod F and attached to the sides of the fname A, the saine being horizontally slotted at a to receive the screws a. Gis a pair of bent arms, turning at their lower ends on the rod F connected at their middle points by a bi'acerod, Gr', from which a spring, H, reaches, and is attached to the rod F. The upper ends of the clamping or feed-arms G are formed into iiattened heads to press against the stave to be finished. The spring H keeps the heads of said arms in contact with said stave.

I do not claim any device shown in the patent of C. B. Hutchinson, February 1, 1853.

Having thus fully described my invention, what I claim as new, and'desire to secure by Letters Patent, is*

The bed-plate E, standard F, rodT, arms spring h., screws a', and slots a, in combination with the concave cylinder B and frame A, the several parts being constructed substantially as and for the purpose specified.
